Peephole Magnifier / Product

Peephole Magnifier
Peephole Magnifier

Peephole magnifier is a new type viewfinder designed on the basis of traditional peephole, through which house owners can rapidly see visitors outside intuitively. No need of arriving in the front of door, it is just to observe through a small hole by getting close to the door.
Peephole magnifier enables us to understand the information outdoor and make judgment conveniently. For the aged people unable to move freely or naughty children ringing the doorbell, peephole magnifier plays its role to the maximum.
